如何使用nginx前端运行两个Docker容器的两个WordPress站点。

我有两个wordpress实例，每个运行一个docker容器。 我想通过一个nginx服务器前端/代理这两个wordpress实例。

以下是我的nginxconfiguration文件。

upstream docker-site1 { server site1_site; } upstream docker-site2 { server site2_site; } server { listen 80; server_name myserver.domain.com; proxy_set_header Host "myserver.domain.com"; # required for Docker client sake proxy_set_header X-Real-IP $remote_addr; #pass on real client IP client_max_body_size 0; # disable any limits to avoid HTTP 413 for large image uploads # required to avoid HTTP 411: see issue #1486 (https://github.com/dotcloud/docker/issues/1486) chunked_transfer_encoding on; location /site2 { auth_basic "Restricted"; auth_basic_user_file /etc/nginx/pass/.site1_htpasswd; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_pass http://docker-site2/; } location / { auth_basic "Restricted"; auth_basic_user_file /etc/nginx/pass/.site1_htpasswd; proxy_set_header Host $http_host; add_header HTTP_HOST $http_host; proxy_pass http://docker-site1; proxy_http_version 1.1; } }

有一个nginx的代理图像，自动代理你的容器。 你可以在这里find它。 像这样运行代理：

 $ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy 

然后，你必须运行一个环境variables你的wordpress图像

 $docker run -e VIRTUAL_HOST=foo.bar.com ... $docker run -e VIRTUAL_HOST=bar.foo.com ... 

或者，最好在你的Dockerfile中添加一个ENV指令并公开这个端口

 # My WordPress 1 Dockerfile ENV VIRTUAL_HOST=foo.bar.com EXPOSE 80

我已经做了使用反向代理与SSL的相同。 首先，您将所有内容redirect到https，然后：

 server { listen *:443 ssl; ssl on; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_certificate /etc/nginx/certs/certbundle.pem; ssl_certificate_key /etc/nginx/certs/server.key; ssl_dhparam /etc/nginx/certs/dhparam.pem; server_name myserver.domain.com; location /site1/ { proxy_pass http://127.0.0.1:8030/; #your wordpress container should have the same port proxy_set_header Host $http_host; proxy_read_timeout 3500; proxy_connect_timeout 3250; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header SSL_PROTOCOL $ssl_protocol; proxy_set_header SSL_CLIENT_CERT $ssl_client_cert; proxy_set_header SSL_CLIENT_VERIFY $ssl_client_verify; proxy_set_header SSL_SERVER_S_DN $ssl_client_s_dn; auth_basic "Area 51 - No trespassing beyound this point without authentication"; auth_basic_user_file sec/htpasswd; } location /site2/ { proxy_pass http://127.0.0.1:8080/; # again, change the port proxy_set_header Host $http_host; proxy_read_timeout 3500; proxy_connect_timeout 3250; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header SSL_PROTOCOL $ssl_protocol; proxy_set_header SSL_CLIENT_CERT $ssl_client_cert; proxy_set_header SSL_CLIENT_VERIFY $ssl_client_verify; proxy_set_header SSL_SERVER_S_DN $ssl_client_s_dn; auth_basic "Area 51 - No trespassing beyound this point without authentication"; auth_basic_user_file sec/htpasswd; } 

在您的第一个网站的wp-config.php中，您应该添加以下几行：

  define('WP_HOME', 'https://myserver.domain.com;/site1'); define('WP_SITEURL', 'https://myserver.domain.com;/site1'); 

确保你已经连接到你的数据库。 我猜你正在使用另一个容器为您的数据库？ 如果是在您的wp-config.php中相应地configuration这些属性

 define('DB_NAME', 'youDbName'); #default is wordpress define('DB_USER', 'root'); define('DB_PASSWORD', 'yourPass'); define('DB_HOST', 'mysql'); # your db container name define('DB_CHARSET', 'utf8'); define('DB_COLLATE', ''); 

没有ssl，它应该差不多一样

编辑：
正如ShanShan所指出的那样，确保你使用-p选项运行你的容器，并且你想为站点1设置端口-p 8030:80
